I got only one reply from Robert Schuhl <robert.schuhl_at_ald-vt.de>
suggesting a possible routing misconfiguration. That was not the problem,
because I use static routing and the Brouter is already our default
gateway, but this warned me for a possible terminal type negotiation
problem. So I found the solution by myself. Just added to the
configuration:
line vty 0 31
terminal-type vt100
Now I can jump into any machine using a X.25 address.
Bye.
